It was an unscrupulous practice in some small factories but it became rampant in China and forced many honest manufacturers to label their boxes "lead-free" after the scandal went mainstream in 2013. It has wide applications in electrochemistry, especially as the positive plate of lead acid batteries. The solid has the NaCl-like structure (simple cubic), which it keeps up to the melting point, 1114C (2037F). PbO 2 is an oxide where the oxidation state of lead is +4 with the chemical name Lead (IV) oxide. The drawback of this method for the production of lead dioxide anodes is its softness, especially compared to the hard and brittle PbO2 which has a Mohs hardness of 5.5. Red lead was used for engineer's scraping, before being supplanted by engineer's blue. It is used in various ways, the most important use is, it is used as a cathode in lead acid batteries. Both the lead and lead oxide are in a solution of sulfuric acid (H2SO4) and water (H2O). It is a powerful oxidising agent. 55) form at temperature 170K (103C). 0000005785 00000 n
Screen capture done with Camtasia Studio 4.0. H Lead oxide (PbO 2, with lead as the Pb 4+ ion) is among the stronger oxidizing agents in acidic solution, but it is comparatively weak in alkaline solution. If a pure compound is desired, PbO can be removed by a potassium hydroxide solution: Another method of preparation relies on annealing of lead(II) carbonate (cerussite) in air: Yet another method is oxidative annealing of white lead: In solution, lead(II,IV) oxide can be prepared by reaction of potassium plumbate with lead(II) acetate, yielding yellow insoluble lead(II,IV) oxide monohydrate Lead (IV) oxide decomposes when heated.
